Former Iowa Governor Tom Vilsack is sending some signals about the future of Hillary Clinton, his choice in the presidential campaign.

On February 23rd of last year, Tom Vilsack ended his campaign for president. Then, on March 26, Vilsack and his wife, Christie, endorsed Clinton’s bid for the White House. Vilsack was named national co-chair of Clinton’s campaign.

It was in that capacity that Vilsack spoke with the Associated Press on Sunday, telling the A.P. that it is "pretty clear" Barack Obama is going to be the Democratic Party’s presidential nominee, and Vilsack said Clinton needs to "acknowledge" that after Tuesday’s contests in South Dakota and Montana. Vilsack told the A.P. Clinton needs to "quickly get behind" Obama.
